JSON to GraphQL

It automatically converts a raw JSON payload into a strictly typed GraphQL schema definition, saving developers hours of manual typing.

The parser recursively analyzes your JSON. Strings become 'String', numbers become 'Int' or 'Float', booleans become 'Boolean', and arrays or nested objects are converted into custom GraphQL Types.

GraphQL is a query language for APIs developed by Facebook. It allows clients to request exactly the data they need and nothing more, unlike traditional REST APIs.

No! The conversion algorithm runs entirely client-side in your browser. Your JSON data never leaves your computer, making it safe for proprietary or sensitive data.

You can copy the generated schema and paste it directly into your GraphQL server implementation (like Apollo Server) to define your API's type definitions.
